Does anyone have any pictures or drawings (other than the brochure that came out in the mid ’20s) of the internals of the Howarth silencer? I have the ends, the outer tube and the centre tube with perforated flange in the middle, but I don’t have the conical pieces that fit either side of the flange as shown in the brochure. What are these like and how were they attached? Any help will be greatly appreciated.

Hello Dave,
The easiest answer may be to substitute the original internals with a straight-through perforated tube to make it the same as a Burgess, and pack some rockwool sound absorbent material loosely around the tube. Dead easy to change the wadding when it gets oiled/carboned up. I have a big file of the drawings of Scott parts that John Underhill drew many years ago. There MIGHT be a Howarth Drawing, and will have a look when I get chance. I’ll let you know if anything turns up.

Thanks Brian, but I’d really like to see/hear how a Howarth performs.
